차세대 엔진 개발을 위한 점보 테스트 제트기 (영문)

2014년 7월 9일

GE항공은 일본항공으로부터 구매한 보잉 B747항공기를 차세대 엔진 개발의 시험용 항공기로 운용중이다. 이 항공기에는 1.5km 길이의 케이블이 내장되어 비행중 개발 데이터를 수집한다.

GE, 베스트셀링 항공기 B737의 엔진을 공급(영문)

2014년 7월 9일

전세계 최고의 베스트 셀링 항공기는 보잉의 B737 시리즈다. 이를 쌓아 올리면 높이가 123km에 달한다. 1984년부터 보잉 B737시리즈의 엔진은 GE와 프랑스Snecma의 합작회사인 CFM International에서 독점 공급하고있다. CFM 엔진을 계량하고 첨단제조기술인 3D프린팅을 이용한 부품 이용으로 차세대 엔진인 LEAP를 개발중이다. 이 엔진은 2017년부터 상용화 될 737 MAX에 장착될 예정이다.

Slice into an additively-made part from @geadditive and you’ll see geometries once thought impossible with traditional manufacturing methods. Why the hype? Engineers can now find greater strength and efficiency through design. #engineering #additive #3Dprinting #manufacturing
Wind, meet water. In Germany’s Swabian-Franconian Forest, you’ll find the world’s tallest (584 ft) and first-ever wind turbines integrated with pumped storage hydroelectric power. So how does it work? At the base of each wind turbine sits a reservoir. Water flowing downhill from the reservoirs will power the hydro plant when electricity is needed. When there’s an energy surplus, the hydro power will push the water back up the hill to the reservoirs, where it will act as a giant battery for the wind turbines. So no matter if the wind is blowing or not, electricity will always be flowing
Spooky season is here, but don't let your annual mammogram scare you. Nearly 30% of women in the U.S. admit to skipping breast screenings out of fear. That's why @gehealthcare engineers decided to better the experience with a mammography system designed by women, for women. Melding comforting design with cutting edge technology, the Senographe Pristina aims to humanize the process for patients, technicians, and radiologists. #BCAM #Mammography #breastcancerawareness
This Ultra Performance Heat Exchanger is a perfect example of how small parts can make a HUGE difference. Still in development, the additively manufactured compact heat exchanger is printed with a high-temperature capable, crack-resistant nickel superalloy that will be able to withstand temps that exceed 1,650°F at pressures >3,600 psi. Good thing, too, because it’s headed straight for the inside of a gas turbine, where it’s projected to deliver a 4% improvement in thermal efficiency for supercritical C02 power cycles while improving power output and reducing emissions. Cleaner, more efficient power generation here we come.
Colder weather is on the way. If you’re in Winnipeg, Canada, that means ice testing is too. There, @geaviation test engines are pummeled with sub-zero winds and ice. The harsh conditions on the ground make sure engines are ready to face the elements in the air. #AVgeek #jetengine #engineering
